Wk180-c feedback

Now the first rifles have shipped, we invite comments from the new owners.This thread is reserved for customer feedback, good bad or ugly. Post photos of your targets, builds etc. Lets keep to first hand accounts please, we reserve the right to edit out comments from non owners.

I probably won't keep the TT in there. But it will be useful to properly group this rifle.

Some initial feedback:

- Build quality is exceptional. Operation is smooth.

- There was a note included about the bolt-stop not functioning correctly with the included PMAG-style mags. It's true. However the bolt stop works correctly with LAR and PCV 50 mags. I have not tested feeding.

- I tried to take off the handguard but stripped 3 of 4 screws on one side. I'm not sure what torque spec or loctite these screws were using, but it seems excessive.

- I don't know if the holes in the handguard were designed as QD mounts, but they are exactly the same diameter as a QD swivel, but slightly too thick to lock. It might have just been the QD swivel I was using, but eventually I was able to get it to lock by filing my swivel and smacking it in.

- The bolt-stop will not fit without modification with the TriggerTech, and possibly other cassette style triggers.

* The interference comes from bottom of the bolt-stop pin radius and the TriggerTech cassette. When you snug the cassette against the bottom of the trigger pocket with the set screws, the cassette rises up enough to prevent the bolt-stop from rotating on it's pin. If you file off a couple thou on the bottom radius of the bolt-stop, it will work correctly.

Hand guard screws are not installed with lock tite but should be snug. Use the correct size allen wrench with square corners to avoidd stripping the heads. As soon as we get our spare part kits, one of which will be included with each rifle, we will forward them out, these include two spare screws, in case anyone looses one. The round holes in the hand guard were never intended to accept sling fittings, some thing we could look at.

Correction, I have learnt that a few early hand guard screws did have lock tite.

The included extractor spring on the right was likely causing the extraction issues. The new one on the left, in addition to the added rubber "donut", should fix extraction.

With the included extractor spring, the extractor pin basically fell out. There was almost no spring tension on the extractor. With the new spring setup the pin took a considerable amount of force to get in, which indicates the extractor is under a lot more tension!

The bolt carrier is phosphated which isn't very slick, so make sure it's coated very well. Don't even use a rag, just apply some CLP and spread it with your fingers. Do the same on your bolt, cam pin, and recoil guide rods. Apply lube in the cam way in the upper and around the locking lugs.
